Well done, rd5rdm
The main purpose of this class is to get some experience in pencil handling. The exact result of for example the chair is of secondary importance. Acquiring pencil handling skills needs time and dedication. But you are on the right track.
Some points to pay attention:
-- don't push on the pencil, work in soft easy strokes
-- there is a strong interaction between the tooth of the paper and the hardness of the pencil: more tooth makes darker values easier but is prone to leave white specks. That can be corrected by combining several layers of different hardness.
you can find a detailed explanation by Ken
-- adapt your technique to the type and style of the work: irregular hatching strokes are OK in sketching. But for "finished" work either the strokes are not discernible (in imitation of photographic work) or in a nice pattern, often "logical" in sustaining the form of the object.
Nice job so far, please move on to class 2
